This strange insect produces a mating song, even though neither males nor females are able to hear sound. How does that work?

This is a Jerusalem cricket (Stenopelmatus sp.). There are several species of Jerusalem cricket in Utah, and the main way to tell one species from another is by the mating song of the male. This "song" is made by rhythmically pounding its abdomen on the ground. While female Jerusalem crickets do not hear airborne sounds, they can feel the vibrations in the ground.
